Layout 2026 lag moving objects

We have an issue with the latest release 2026 in Layout.

Considerable lag moving objects (shapes), and typing within text boxes.

Often up to 30 seconds to move an object. Layout locks up until the object moves.

Worse if using arrow keys - sometimes lag up to 15 seconds. Resizing/deleting an object is also slow. Typing text within text boxes is a few seconds lag.

This is making this release unusable for us. If we revert the file back to 2022, it is fine.

Occurs irrespective of which computer we use, skp file, wifi network.

Current test file is only 41mb with 1 viewport to a skp model 33mb

Is this a known issue for others?
